KOL count: 29 → 25 across marketing/SEO copy

Backend KOL_FEEDS trimmed from 29 to 25 (dead feeds removed).
Sync all hardcoded count mentions:
- layout.tsx JSON-LD, page.tsx (metric + comparison + copy)
- kol/page.tsx, KolPageClient.tsx ("and 26 more" → "and 22 more")
- glossary/page.tsx, opengraph-image.tsx
- public/llms.txt, llms-full.txt
- drop removed KOLs (Dragonfly Capital, Nic Carter) from named lists

Bundles other in-flight frontend work already in the working tree.
